I can't see anywhere in the question where it says this is supposed to be for 2012. Presumbly, it was thought that it's enough that TRY_PARSE and PARSE don't exist in 2008R2, however a hint would have been nice.
I believe it should always be stated what version of SS the question addresses. Assumptions are always bad and there is no place for it in these questions.
